Performance of Communication Systems

This book is about efficient communication. The role of communication, as a means for the transmission of information among people, is one of the key factors driving the development of our civilization. There are numerous examples where new achievements in the communi cations area had a crucial impact on our society. The human language can be considered as one of the first steps for the efficient delivery of informa tion between people. Similarly, the influence of other milestones like written communication, bookprinting, telegraphy and the telephone and television system was essential. Facilities for quickly accessing existing information and for the fast delivery of information have become one of the most important economical factors nowadays. Clearly, fulfilling the ever-increasing demand for fast, cheap and reliable communications represents itself an important industry, leading to substan tial technical achievements in this area. After only being used by an "infor mation elite" in the beginning, developments like the telephone system and the Internet quickly spread and are now widely accepted, as witnessed by the ubiquitous presence of mobile phones and Internet applications like the World Wide Web.

High practical importance in the field of telecommunications and computer networks Monograph is based on both theoretical investigations and industrial experience Includes supplementary material: sn.pub/extras

Klappentext
This book provides an extensive approach to support the planning and optimization process for modern communication networks. Based on an analysis of the key properties of modern network architectures, a set of requirements for such approaches is derived. A model-based performance evaluation approach is suggested, where highly-efficient matrix-geometric methods are employed in order to circumvent the drawbacks of existing numerical and simulative approaches. The book contains a thorough survey and a detailed comparison of state-of-the-art numerical algorithms in the matrix-geometric field. A high-level modeling approach based on stochastic Petri nets is developed in order to simplify the specification of complex models. To illustrate the approach, several case studies are presented, covering application areas from ATM networks to World Wide Web traffic and TCP/IP networking.
